During shifting events such as when using JoyStick Piloting for Outboards and/or shifting into gear, the Flo-Torq SSR HD rotates both port and starboard - eliminating shift clunk and vibration for quiet and smooth shifting. Once under load, the hub will engage the propeller inner hub, resulting in a solid hub with the ability to transfer the power of

Flo-Torq SSD HD can be used on all high-horsepower applications such as center console, bass, multispecies, bay/flats, deck, tritoon/pontoon, RIB, and sport boats. It can be used with Mercury propellers Bravo I, Enertia, Enertia ECO, Fury, Revolution 4, Mirage Plus, and Tempest Plus.

Fine tuned.

Just by varying the size of the exhaust hole and controlling your engine’s rpm, you can eliminate sluggish performance or compensate for changes in load in altitude. And it’s technology that you can only get with Mercury Propellers.

Producing world-class Mercury propellers is no simple task

Producing a world-renowned Mercury Marine prop takes time and skill, not to mention advanced engineering and know-how.
Three dozen Mercury employees create some of the best props in the world. Every operation - from inception to completion - is centralized at Mercury's propeller manufacturing facility in Fond du Lac, Wisconsin.
